Meristematic tissue have the ability to
divide themselves. It is the primary site for cell division and cell
differentiation. It produces the new cells and are called growing tissue in
plants. The new cells may or may not divide. It is the source of the regenerative
potential of the plant.

Cancerous cells can originate anywhere in the
body and can spread into or invade adjoining tissues. It keeps growing and dividing
relentlessly to form lumps. It can also break off and travel to distant

Answer:
Proteins is a macromolecule that helps to send signals
Explanation:
Before a chemical reaction, the elements and compounds which are about to take part in the reaction are known as reactants.
And, when the chemical reaction takes place between the given elements and compounds then they change into products.
For example, we take sodium and chlorine elements and before any chemical reaction they are the reactants.
But when a chemical reaction takes place between sodium and chlorine then it results into the formation of sodium chloride which is the product.
Answer:
Excretion
Explanation:
The excretory system removes cellular wastes and helps maintain the salt-water balance in an organism. When cells break down proteins, they produce nitrogenous wastes, like urea. The excretory system serves to remove these nitrogenous waste products, as well as excess salts and water, from the body.
